Missionaries often struggle with isolation — in fact, 67% report moderate-to-significant levels of depression from it.^1 Prayvine is a free, secure prayer request communication platform built specifically to bridge that gap between mission workers and the people who support them.
Unlike traditional email newsletters that get lost in cluttered inboxes, Prayvine organizes prayer support into private "prayer circles" — encrypted, ad-free spaces where missionaries can share real-time prayer requests and life updates with a single click.^2 Supporters receive notifications and can respond instantly, replicating the warmth of in-person group prayer in a digital format. The platform also helps energize fundraising: 68% of ministry partners report being more likely to donate when they're actively engaged through Prayvine.^3
Founded in 2014 by Ian and Kim Hsu — missionaries based in Orlando, FL — Prayvine is a registered 501(c)(3) nonprofit, completely free and 100% donor-funded.^4 Ian previously led digital engagement strategy at Stanford University and has been cited in The New York Times, TechCrunch, and Mashable. Kim is a former staff worker with CityTeam Ministries.^1 Today, over 1,000 missionaries and 100,000 prayer partners use the platform, supported by the Hsus' home church, Peninsula Bible Church in Silicon Valley.^5
